I have a 02 7.3 4x4 and it's stuck in 4x4 low. It was stuck in 4x4 hi until I shifted it into low. It has been very cold and icy here but now it's above freezing and I'm still stuck. Any Ideas?

oops, It's semi auto hubs and flip a switch 4x4.

 

I don't know what you mean by semi auto. Put it in 2wd, backup a few feet, put it in nutral and let it have enough time to let in shift. I don't have enough information to help yet. Do you have manual hubs with auto switch?

 

They are auto hubs but I can lock them manually unlike a 350. I have ESOF switch on the dash. It went into 4hi and then would not go out. I backed up and did everything. I put it in low to see if the actuator would move and it went into low but now it will not go back to 4hi or 2wd. (now I'm screwed) I tested the switch on the dash and I get different resistence settings for each posistion. Vacumn lines seem ok and all 4wheels are turning.

 

Change the two relays under the hood.They might have moisture in them.They should be on the drivers side fender/firewall area. That's what was wrong with mine.
